Hymenoptera in My Garden

0912171558

For those with a fear of bees (apiphobia) or wasps (spheksophobia), now is not a good time to hang out in my garden. The overgrown sedum, in particular, is crawling with pollinators, one on top of another: bumblebees, wasps, hornets, flies, and the occasional moth or butterfly (just to tone down the terror factor a notch).

The sedum is called “Autumn Joy.” I guess I forgot to ask, “Whose joy?” Not my husband’s, certainly, but maybe these guys’?

In another flower bed just a few feet away, I noticed a large concentration of wasps investigating my tiger lilies.

At first, I wasn’t sure what could be so interesting about these bare stems, the blooms having vanished almost two months ago now. When I went in for a closer inspection, however, I found hundreds of tiny insects beneath the leaves.

These purple spotted lily aphids (macrosiphum lilii), destructive little pests, apparently make a fine meal for the visiting hymenoptera. So, while I don’t generally make it a point to encourage wasps to gather near my deck, I’ve decided to make an exception and let them feast for as long as they like. Because it’s nice when the garden takes care of itself.

Out front, I found another insect predator grappling with its insect prey. Generally, I see cicada killers (sphecius speciosus) hovering near their holes in the hardened mud by the river, but the droning buzz of cicadas had drawn this one into my front yard, where, despite its generous size, it was struggling to lift a cicada and transport it back to its nest.

My boys and I watched for a few minutes, (giving me time to feel a little sad because I happen to like cicadas and have written about them before) then went back to our work in the driveway. I even forgot about it until a sparrow flitted past my view carrying something large in its beak. When it landed on my front walk, I saw it drop a cicada, which it began to devour quite happily. Bird trumps insect. This time, anyway.
